Large Planter Boxes

(19 products)

Large planter boxes give a space a straight edge. Where a round pot is an object you place, a box is a line you draw: along a frontage, down a terrace, between a seating area and a walkway.

These are the nineteen box-form models we carry that run 30 inches or longer, from an 8 inch tall sill box to a 42 inch tall screening box, and up to 100 inches long in a single piece.

Large planter boxes, by length and height

Two numbers decide a box, and they do different jobs. Length decides how much of the run one planter covers, and therefore how many you buy. Height decides what the box does once it is there.

Sizing a large planter box: length first

Our boxes start at 30 inches and the longest single piece, the Hudson, is 100 inches. Measure the run you want to cover and divide, remembering that two planters set end to end read as a line while three or more read as a wall.

A long box is not the same as several short ones. One 72 inch planter has a single soil mass that dries more slowly and holds a hedge more evenly than two 36 inch planters with a seam in the middle. Against that, two shorter pieces are far easier to carry, to turn through a doorway and to reposition later.

Height is the job

8 to 12 inches is a sill or edge. The Salon Box at 8 inches and the Cuba Low and Antwerp at 12 define a boundary without blocking a view, which is what you want along a low wall or under a window.

18 to 24 inches is the working height, where the planting starts above knee level and reads from a seated position. Miami, Torino, Panama, Tolga, Hollywood and Milano sit in this band.

32 to 42 inches is a screen. Amesbury, Brisbane, Delray and Potsdam at 32 inches, Perth and Darwin at 42, put the soil line near waist or chest height so the planting starts where a sightline already is.

Empty weights across the nineteen run from 12.3 lb for the smallest Salon Box to 124.4 lb for the largest Darwin. Every exterior dimension, interior opening and empty weight is published on the specifications page.

What a large box does not do

It does not hold as much soil as it looks like it will. The interior opening is smaller than the exterior on every model, because the wall has thickness and most forms taper. Work from the interior figure when you are matching a nursery pot, not from the name.

It is not meant to be filled with soil to the bottom. Jay Scotts call for lightweight filler in the base rather than heavy garden soil or fine sand, and some models take an internal shelf so a nursery pot sits near the rim. That keeps the weight down and the planter movable. Our guide to filling a large planter covers the method.

Length is what makes it awkward, not weight. A 72 inch box weighs less than most people expect and still will not turn on a stair landing. Measure the route in before you measure the terrace.

Drainage, finish and freight

Boxes are not drilled unless you ask. Jay Scotts add drainage holes free of charge at order time, one to two inch holes roughly every 12 inches, which on a 60 inch box is four or five. A drilled planter is final sale. See the drainage guide.

All nineteen are finished to order in any of the 20 standard colors or a custom match, with an automotive-grade paint system. Custom color orders are final sale.

Frequently asked questions

What counts as a large planter box?

In this collection, a box form measuring 30 inches or longer. They run from 30 to 100 inches long in a single piece, and from 8 to 42 inches tall.

How long a planter box can I get in one piece?

The longest single piece we carry is the Hudson at 100 inches. Several other models reach 60 to 72 inches. Beyond that you are setting two planters end to end, which reads as a continuous line if the heights match.

How tall should a planter box be?

Eight to 12 inches marks an edge without blocking a view. Eighteen to 24 inches is the general working height. Thirty two to 42 inches screens, because the soil line starts near waist or chest height before anything is planted.

What do I put in the bottom of a large planter box?

Lightweight filler, not heavy garden soil or fine sand. Jay Scotts are explicit about this in their owner's guide: filling a deep planter entirely with soil adds weight you do not need and does not help the planting. Some models also take an internal shelf so a nursery pot sits near the rim. ⛔ Do not use gravel as a drainage layer; it makes drainage worse, not better.

How much does a large planter box weigh?

Empty, between 12.3 lb and 124.4 lb depending on the model and size. Filled weight depends on what you put in it, and the filling is far heavier than the planter. Every published empty weight is on the specifications page.

Is one long planter better than two short ones?

For the planting, usually yes: a single soil mass dries more evenly and holds a hedge better than two with a seam between them. For handling, two shorter pieces are much easier to carry, turn through a doorway and move later.

Will a planter box work as a privacy screen?

A 32 or 42 inch box gets the soil line to roughly waist or chest height, so the planting starts where the sightline already is. The screen is the planting, not the planter. Our tall privacy planters collection is the narrower selection made for running in a line.

Do planter boxes come with drainage holes?

Not unless you ask. Jay Scotts add them free of charge at order time, to their standard of one to two inch holes roughly every 12 inches. A drilled planter is final sale, so decide before ordering.

Can I use them on a roof terrace or balcony?

Often, but planted weight is the constraint rather than the planter, and a structural engineer confirms what the structure carries. Access matters too: a long box may not turn on a stair. See rooftop planters: weight, access and wind.

Do they come in matching colors?

All twenty standard colors, across matte, gloss, satin and metallic, or a custom match. Order a run together and it is finished in the same batch, which is the best way to keep a line consistent. Jay Scotts note that because the planters are finished by hand, weights and dimensions can vary slightly.
